Abstract (en)
[origin: EP1394988A2] A preset data storing means (108) stores identification data of the user's own subscribed hot spot data and identification data of a hot spot dealer in roaming contract relation to the own hot spot dealer. A wireless communication means (107) obtains the electric field intensity of a channel as a subject of survey and identification data of a dealer. A means functions, when the obtained identification data is identical with the identification data user's own subscribed hot spot dealer as stored in the preset data storing means, to display on a display means (105) that the obtained identification data is the identification data of the user's own subscribed hot spot dealer such that the user can understand the displayed content at a glance, and when the obtained data fails to be identical with the roaming contract relation hot spot dealer, to display on the display means (105) that the obtained electric field intensity is that of the roaming contract relation dealer such that the user can understand the displayed content at a glance. <IMAGE>
